Graphene oxide and reduced graphene oxide nanocomposites.

A new study focuses on the fluid properties and corrosion resistance of nanocomposites based on graphene oxide and reduced graphene oxide
in this study, the effects of graphene oxide (GO) and reduced graphene oxide (rGO) nanoparticles on the corrosion protection properties of nanocomposite coatings with particle mass concentrations of 0.25% to 1% in epoxy substates were studied in detail. In addition, the effects of the distribution of GO and rGO nanoparticles in epoxy substates on the corrosion properties and fluidity of coatings were studied by mixing nanocomposomes with ball mills of 24 h and 48 h. The surface morphology of the coating is analyzed with a field emission scanning microscope

GO/ Epoxy nanocomposite coatings are hydro-hydro-friendly
oxygen-based clusters in graphene structures, the effective distribution of nanoparticles in the substate, and the doping of nanoparticles affect corrosion protection. Of all nanocomposate coatings, the best corrosion protection is 0.75 wt%rGO/epoxy nanocomposates, which are ground for 48 hours. GO/epoxy nanocomposing coatings exhibit hydro hydromassiveness in all mass fractions and mixing times. However, adding 0.5 and 0.75 wt% rGO and grinding for 48 hours produces hydrophobic nanocomposics. At a concentration of 0.75 wt%, rGO nanoparticles have the best dispersion properties.
nonlinear flow measurements show that, contrary to nanocomposomes containing GO particles, rGO/epoxy nanocomposives exhibit non-Newtonian shearing and thinning behavior at the mass concentration and grinding time studied.
the study has been published in the Journal of Coating Technology and Research, Volume 17 of 2020.
